43-inch 4K VA monitor for productivity

The ViewSonic VX4381U-4K is a 43-inch computer monitor with a 3840 x 2160 resolution and a VA panel that delivers a 4000:1 static contrast ratio. It targets professionals who need a single large screen for document editing, graphic design or multitasking. HDR10 support expands colour and contrast range for compatible content. The flat anti-glare surface reduces reflections in bright offices.

Check video outputs and USB-C power needs

Verify that your computer can drive 3840 x 2160 at 60 Hz over HDMI 2.1 or DisplayPort 1.4 before ordering. The USB Type-C port supplies up to 65 W of power delivery, so confirm your laptop accepts charging at that level if you plan to use one-cable docking. Four USB-A ports and one USB-B port require a host connection to function as a hub. Audio output uses a 3.5 mm jack.

Included cables enable immediate multi-device setup

The box provides an HDMI cable, a USB-C cable and a USB-A/B cable so you can connect video, data and 65 W charging without buying extras. MultiPicture mode splits the 43-inch area into up to four simultaneous windows from different inputs, turning the supplied cables into a ready-made KVM-like workflow. Eco-mode adjusts brightness to lower power draw during long sessions. A quick start guide covers initial configuration.
